Slope=rise/run
we see that the slope will be negative
it is more accurate the farther we are apart
we wiill use the points closest to the line, those are (3.5,3.5) and (5,1)

slope between (x1,y1) and (x2,y2) is (y2-y1)/(x2-x1)
for this one
(1-3.5)/(5-3.5)=-2.5/1.5=-1.666666666≈-1.67

the slope is -1.67

If alvin sold 60% of his baseball cards, gave away 30% of those that were left, and still had 40 baseball cards in his possessio
kipiarov [429]

Answer:

The number of baseball card to begin with is 143

Step-by-step explanation:

Let The number of baseball cards = x

The number of sold baseball card = 60% of x

                                                         = 0.6 x

The number of left baseball card = x - 0.6 x = 0.4 x

The number of card gave away = 30 % of left cards

                                                     = 0.3 × 0.4 x = 0.12 x

The number of card left in his possession = 40

So, 0.6 x + 0.12 x + 40 = x

Or,  40 = x - 0.6 x - 0.12 x

Or,  40 = 0.28 x

∴   x = \frac{40}{0.28}  =  142.85 ≈ 143

Hence The number of baseball card to begin with is 143  Answer

Area of sector................................
sveticcg [70]

Answer:

A ≈ 25.1 cm²

Step-by-step explanation:

the area (A) of the sector is calculated as

A = area of circle × fraction of circle

  = πr² × \frac{\frac{4\pi }{9} }{2\pi }

  = π × 6² × \frac{\frac{4\pi }{9} }{2\pi }

  = 36π × \frac{\frac{4\pi }{9} }{2\pi }

  = 18 × \frac{4\pi }{9}

  = 2 × 4π

  = 8π

  ≈ 25.1 cm² ( to the nearest tenth )

b=a+3\\&#10;c=a+6\\&#10;a^2+b^2=c^2\\\\&#10;a^2+(a+3)^2=(a+6)^2\\&#10;a^2+a^2+6a+9=a^2+12a+36\\&#10;a^2-6a-27=0\\&#10;a^2-9a+3a-27=0\\&#10;a(a-9)+3(a-9)=0\\&#10;(a+3)(a-9)=0\\&#10;a=-3 \vee a=9\\&#10;

The length can't be negative, so the answer is 9 cm.
